Starting this weekend, Qdoba will set up "Flavor Flags" around Royal Oak and you could win free burritos for a year if you find one.
The promotion coincides with the opening of the chain's new location at 30754 Woodward Avenue in Royal Oak.
If you find a flag, bring it to the new location during its Grand Opening on March 26th starting at 10:30 a.m.
The first 13 people who bring in a flag will win one free entree per week for 52 weeks. Other prizes will be available as well.
The chain hints that flags could be hidden around locations like the Detroit Zoo, Oakland Community College and Mark Ridley's Comedy Castle.
The chain will be hiding 100 flags from March 19th through the 25th.
You can check out the chain's facebook, twitter or instagram pages for more clues throughout the promotion.
